[Closed] Exclude all nested layers within a specific layer

Hi guys

I have a script that switches layers on. Works great even for nested layers


    lMask = "_"

    fn switchOnObjectLayers = 
    (
        for i = 0 to layerManager.count-1 do
        (
            local ilayer = layerManager.getLayer i
            local lname = ilayer.name

            -- Switch on all layers except for these: 0, Any layer starting with '_', any nested layer
            if (((matchPattern lMask pattern:(substring lname 1 1)) != true) and (toUpper lname != toUpper "0") and (ilayer.getparent() == undefined)) then ilayer.on = true
        )
    )

However, I want to EXCLUDE ALL nested layers no matter how deep, from 1 specific layer called “MainLayer”. For the life of me I can’t seem to
find a way to do this seemingly simple thing

is it not easier to find a layer (protected) by name first, store its #on state, set all layer to value you want, and restore a protected layer ?


main = layerManager.getLayerFromName "MainLayer"
val = if main != undefined do main.on
for k=0 to layerManager.count -1 do (layerManager.getlayer k).on = state
if main != undefined do main.on = val

Hi Denis

Thanks for the reply. However I’m not sure I understand what you are saying

Running you code gives me this result:
– Error occurred in k loop; filename: ; position: 159; line: 3
– Frame:
– state: undefined
– k: 0
– Unable to convert: undefined to type: Boolean

<state> is what you want to set. it’s a pseudo parameter in my code… replace it with ON for example

if I for example declare state in the beginning as true, then I get an error about “on” being an unknown property…

We replied at same time

If I change it to “on” I still get:
Unknown property: “on” in undefined (line 4)

fn setAllLayersOn state = 
(
   for k=0 to layerManager.count-1 do (layerManager.getlayer k).on = state
)
fn setLayerOn name state = 
(
   if (layer = layerManager.getLayerFromName name) != undefined do layer.on = state
)
setAllLayersOn on
setLayerOn "MainLayer" off

I still get this error:

– called in setAllLayersOn(); filename: ; position: 103; line: 3

– Unknown property: “on” in undefined

i fixed the code … it has to be layerManager.count-1

Thanks Denis

But that still pretty much works like I have it in my 1st code example

I need to exclude ”MainLayer” from being switched on as well as any nested layers inside it from being switched on. getparent and getchild gets me 1 layer deep only. Anything deeper and I can’t get it to work.

So I want to switch ON all layers including all nested layers, BUT EXCLUDING “MainLayer” and any nested layers inside it no matter how many levels deep
